Abstract

The acoustic transmission channel has a unique place in the information transfer in all spheres of life. The dominant position acoustic communication today keeps prsonálním process information transfer. Yet achievable intelligibility in classrooms, lecture halls and a congress does not pay close attention. The existing research results show that measurement of the speech transmission index Stipe can not agree with logatomickými tests for evaluating the transmission properties of instructional space and the measurement results are dependent on the characteristics of the directional measurement microphone. Article presents preliminary results of comparative research on the influence directional characteristics of wave sensor, which simulates binaural hearing mono signal to the measured values STIPA and CIS.
